It was great and it around technical and dsa along side projects focus on technical plus hr questions, puzzle were included too guesstimate were pretty tricky despite the dsa questions
Very easyError Handling:
Implement robust error handling mechanisms, including centralized error handling, proper logging, and meaningful error responses to clients.
Input Validation:
Validate all incoming data to prevent security vulnerabilities and ensure data integrity.
Rate Limiting and Throttling:
Protect your API from abuse and ensure fair usage by implementing rate limiting.
Scalability:
Asynchronous Operations:
Leverage Node.js's non-blocking I/O model for efficient handling of concurrent requests.
Load Balancing:
Distribute incoming traffic across multiple instances of your API to handle increased load.
Database Optimization:
Optimize database queries and use appropriate indexing to improve performance.
Caching:
Implement caching strategies to reduce the load on your database and speed up data retrieval.
Microservices Architecture (Optional):
For very large applications, consider breaking down your API into smaller, independent microservices.
I applied online. The process took 5 days. I interviewed at Nones (Dindigul) in Jun 2024
